This project started as a SE KT88 amp. All holes are drilled, chassis painted...As an afterthought I tested the power xfmr and found that I got 1120VCT instead of 1000vct that someone had labeled. Choke loading +losses would have given me ~ 410vdc. Now I anticipate ~ 490vdc (choke loaded). The ? is, now what; the original design is now in the scrap pile. What would you do with 490vdc and Tango XE 20s.
